Super compact microstrip line and CPW filters based on left-handed (LH) metamaterial medium for RF and microwave applications are presented and demonstrated by the full wave simulation and experimental results. The microstrip bandstop filter has a centre frequency of 1.164 GHz and a fractional bandwidth of 0.51%. The loaded quality factor of the filter is 197. The filter is more than 4 times smaller...
In this paper, a super compact integrated multilayer left-handed transformer matching 17.5 Omega to 50 Omega at 2.4 GHz with over 40 dB is developed. The size of the LH transformer is over 25 times smaller and the operating bandwidth is twice wider than that conventional quarter wave transformer at the same operating frequency.
Integrated left-handed (LH) metamaterials on GaAs RF/MMIC technology are presented. LH unit cells, transmission lines and filters are fabricated and characterized, showing that a step improvement in RF/MMIC size reduction can be achieved using LH technology. In addition, integrated LH circuits have exhibited broader operation bandwidth
A GaAs solid state passive coplanar waveguide (CPW) left-handed metamaterial medium is proposed and validated by measured results. The unit cell of the fabricated structures has a size of 0.09 mm2. The left handedness range of the solid state left-handed structure extends from 2.3 GHz to 17.5 GHz. The compactness and broad left-handed operating bandwidth make the presented left-handed metamaterial...
